- Application filed A ril 26. 1905. Serial No. 267.611.

-To all whom it may concern:

Be it known that 1,. GEORGE AUBREY LEE,

a citizen of the United States, residing at Yonkers, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Machines for Packaging Material, of which the following is a specification. E

My 'present'mventlon pertains to improvea ments in machines for packaging loose substances, particularly granular or fiakymate I rial such astobacco. and the like.

The invention will be best understood uppn reference to the annexed drawings, w erem:

The main object of my invention is to produce a compact and efficient machine for the purpose in View, that is, accurately weighing the material tobe packed, filling the package, compressing the charge, closing and sealing the package, and, finally, if desired, applying a stamp or band to the package thus closed.

With the particular embodiment of the in vention herein shown the machine is espe.

cially adapted to the handling of granular or flaky material, such for instance as scrap tobacco or cigar cuttings. In packing tobacco in paper bags, two bags are used, one nested within the other, the inner bag being prefer ably waterproof.

The essential features of the machine com: prise two overlapping turrets or carriers which work in conjunction with each other, one being a form-carrier which presents the form with the bag or bags thereon to the feed hopper and then carries it in line with the underlying package-carrying turret. This second,turret, which receives the bag with the compressed charge, then presents said charged bag to folding and closing mechanism, after which the closed package is automatically presented to a previously-pasted and automatically positioned stamp or label which is automatically applied to the infolded end of the package. The packages thus completed are transferred through the action of the machine to a carrier, where they are retained a sufficient length of time to permit the paste employed to become thoroughly dried.

A still further feature of merit in the present machine resides in the means employed for automatically presenting the bag forms, with the bags thereon, to the turret and likewise discharging the empty and stripped forms from the turret and moving the same out of the path of rotation of the turret.

Other features of construction and design which are of material advantage aie also present, and will be hereinafter more fully set forth and pointed out.

Referring to the drawings, 1 denotes the bed or table of the machine, supported by suitable inter-connected and braced legs 2 and 2, secured to the under side thereof, the parts being madesufliciently heavy to render the machine stable and to afford proper support and bearings for the power shafts and the like.

Secured to and extending upwardly from what may be termed the rear of the bed or machine is a column 3, carrying at its upper end a cross-head 4, to which in turn are secured a series of horizontally-disposal arms 5, see Figs. 1, 2, 7 and 8. The outer end of each arm is bifurcated, the inner walls being flat and standing parallel to each other. Each arm (excepting the outermost ones) is provided with a vertically-disposed secondary arm or branch 6, the upper end of which is formed with a head 7, towhich are secured by tap belts or the like the laterally-extending lugs 8 of the measuring chambers 9.

Each chamber is likewise provided with a.

through shaft 1.0, the ends of which are flattened and rest within the bifurcated ends of the two adjacent arms 5. As will be readily appreciated, any one of the series of measuring chambers may be removed, 'independently of the others, without afiecting the operation of those remaining in position, which much as except as above described, the con struction is essentially the same as that shown, described and claimed in Letters Patent granted to Rufus LJ-Patterson under date of March 15', 1904, and numbered 754,937.

Each measuring chamber discharges'into a scale-pan 11, whichin turn empties into a common hopper 12, the mouth of whichstands in line with'the form-carrying turret hereinafter referred to. The measuring devices are actuated by rods 13, connected at their lower ends to the outer ends of levers 14, which are raised and lowered by cams 15, mounted on a shaft ,16 to which motion is imparted by an intermediate shaft 1.7 (see Figs. 5 and 6), said shaft receiving its motion from the main cam-shaft 18. 'The dribble rolls (not shown) are driven through belts 19 and 20, the .latter passing about and receiving its motion from a pulley 21, mounted on the main driving shaft 22, see Fig. 3. Said mainshaft and the cam shaft 18 are mounted in suitable bearings carried by the supporting frame, and stand parallel to each other, see Figs. 4 and '5. The main shaft 22 is provided with a fly-wheel 23 at one end, and is likewise provided with a clutch member 24, slidably mounted thereon, 'which works in conjunction with a similar member 25, formed upon the hub of the loose driving pulley 26. The slidable clutch member is actuated through a yoke piece 27, fulcrumed at its upper end to an arm or bracket 28, extending outwardly from the bed or table. A rod 29 connects the lower end of the yoke to an arm 30, said arm in turn being'secured to a shaft 31, ournaled in brackets 32, 32, Fig. 4, an actuating lever 33 being secured to the opposite end of said shaft and, projecting upwardly thereon at the right hand side of the table in easy. reach of the attendant who places the forms, with the bags thereon; upon the form-feedingdevicel\lotioi1 is transmitted fromthe main shaft to the cam shaft through a pinion 34, mounted on the former, which meshes with a large gear 35 carried. by the cam shaft. Secured to said shaft are four cams, designated as 36, 37, 38 and 3-9. (am 36 serves primarilyto rotate the turrets, to revolve the package tumbler and the stan-ip-feeder. Cam 37 operates to raise and lower the form-carrying turret; ,cam 38 :wtuates the stamp-presenting or )ositioning mechanism, the side hunter, and also the package-elevator;.and cam 39 acts to raise and lower the shaft or column which carries thepacker, the folder mechanism, the paste .receptacle and the p ackage-removing re d The camshaft 18 has secured to the end i adjacent to the lefthand side of the maried by the supporting member 2.

,chine a bevel gear 40, which meshes with a similargear 41 secured upon a shaft 42, Figs. 1 and 4, mounted 1n suitable hangers 43, car- Said shaft 42 likewise carries a cam 44 which in a manner hereinafter setforth actuates the form-withdrawing and j and also the endbunter';

The bed or table is provided with an open ing at approximately the center'thereof, and a hollow column or post 45 is secured to the table at this point, the'loy gerend, ofthe column extending into the open ing, .makjpg a neat fit therewith, while thelaterally-ex presenting devices tending flange of thecolumn has "a fainibearing upon the up er fade ofithe tableto. which it is bolted, see i having a laterallyrprojecting flange which rests u on the u per end of the column, extends ownwa'r y through the column, the inwardly-projectin portions of said column being bored and ressed so' as to afford a.

smooth bearing for the sleeve. The lower end of said sleeve is reduced and a washer 47 surrounds the up er part of the reduced portion, lying imme iately below the lower end under face of the bed. A ear 48 is splined upon the sleeve while the lower end of the sleeve is provided With a series of ockets 49, which in effect form ratchet teet see Figs. 17 and 19. The sleeve immediately above the pockets 49 is formed with an annular groove in which works a pawl-carrier 50, made of two pieces and secured in place as illustrated in Figs. 17 and 20. The upper end of the sleeve is bored out and a bushing 51, having a square opening extending therethrough is shrunk therein. A washer 52 overlies these parts. The lower end of the sleeve is provided with a cylindrical bore, and a shaft 53 (the lower portion of which is cylindrical in cross-section'while the upper portion is square) extends throu 11 the bushing and sleeve in a manner best i lustrated in Fig. 3*. From this it will be seen that any rotary motion imparted to the sleeve will be transmitted to the shaft, while the latter may be freely moved endwise through the sleeve and bushing.

A lever or arm 54 is fulcrulned between two upstanding lugs 55, formed upon a crossquarter revolution. 7

An arm or lever 59, Figs. 2, 3, 4 and 5, fulcrumed upon a shaft 60, carries a bowl 61, which overlies-the cam 37, the outer end of the arm being connected to a link 62 which in turn 1s connected to a swivel block 63,'Fig. 1, mounted in the lower end ofshaft53. Cam 37 is so timed as to elevate 'the-shaftprevious to a rotation thereof through the action of cam 36, as just described; The purpose of this will resently a pear.

Secure y mounte upon the upper end of shaft 53 is a castin or turret 64, provided with four radiallyisposed, equally-spaced wise provided with four depending hollow lugs or hubs 66, spaced midway between the adjacent funnels. The funnels by preference "will be formed separately from the turret, as indicated most clearly in Figs. 12 and 15, be,- ing provided with laterally-extending flanges which rest upon-the upper face of the turret frame 0rjcasting,while the lower contracted 'portion': makes a close fit with the walls of ways or recesses formed in the turret frame two downwardly-extending hooks 67, pressed as a consequence the shaft 53 will make a bar 56, extending from one leg or support to hoppers. or funnels 65, the turret being likeor casting. Eachfunnel is provided with 65. of the column and overlappinglagainst the inwardly at their lower ends toward each extend out from each side of the funnel orllared upper portion of the shape or holder, said wings. serving to support the shapes when they are positioned preparatory to being taken up by the turret after having the bags placed thereon,'and also when the holders with the bags stripped therefrom are discharged from the turret. Adjacent to the station designated by 71, Fig. 5, and termed the .feed or shape-feed station (at the left of the machine), and also at the station designated by 72 and termed the discharge station are located suitable tracks and actuating mechanisms or devices for positioning and removing the shapes.

At the feed station, Figs. 1, 2, 5, 14 and 15 is provided a fixed back or support 73, sustained by suitable arms secured to the bed or table. 74 designates the movable track or support which stands parallel to the fixed track 73, and is connected to a slide 75, mounted and movable longitudinally in a way formed in the fixed member or guide 76. The movable track, as will be seen upon reference to Fig. 14, is of a length equal to that of two of the funnels of the bag-shapes, and is provided with an upstanding lug or ear 77 whleh engages a wing 70 and moves the forms with the two superimposed bags thereon inwardly toward the turret, the innermost form being directly positioned beneath the funnel 65, which stands at that time in exact alinement therewith. Each track is provided with a cutaway section or recess 78, which when" the movable track reaches its innermost limit stands in line with the hooks or latches 67, said latches riding over the wings 7 as the turret is lowered, and engaging the under face thereof. As the turret rises into the position shown by dotted lines, Fig. 2, the form, with the bags thereon, is raised with it. The formdischarge mechanism is of substantially the same constructicm, comprising a fixed track 73, a movable track 74, a slide 75, a guide or member 76, a lug or ear 77 placed in this instance at the inner end of the movable track, and recesses 78. The tracks and beveled recesses in this instance are so proportioned as to cause the latches to ride from beneath the wings and thus free the form, see Fig. 12, when the turret is lowered. The movable track is then moved outwardly, withdrawing the shape from beneath the turret hopper or funnel 65.

To effect the reciprocation of the movable tracks or supports, the following mechanism is employed, particular reference being had to Figs. 1', 2, 3, 4 and 17. .livotally connected to the lower portion of the supporting member 2 'is an arm or lever 79, pin-jointed at its upper end to a lever 80, which in turn is secured to-a shaft 81 mounted in suitable brackets carried by the under face of the table. -An arm 82 secured upon the shaft extends through an opening in the table and is connected to the movable or reci 'n'ocating track 74 through the medium of a link 83. Shaft 81 is provided with a bevel pinion 84 at one end, which pinion meshes with a similar pinion 85 carried by a shaft 86 which stands at right angles to shaft 81, see Fig. 17. Shaft 86 carries an arm 87, which also projects upwardly through an opening formed in the table and is connccted'to the movable track section 74 by a link 88. The parts are so timed that the turret 64. moves upwardly to its full extent, carrying with it one of the shapes or bag-forms previously positioned upon the tracks 73, 74, and automatically engaged by the hooks 67, and is then given a quarter turn. As the turret begins its upward travel, the movable tracks or supports are moved outward, track 7 4 being placed in position to receive another form, and 7 4. traveling outwardlywith the stripped form, which may be lifted off by the attendant at station 72. Before the turret is again lowered the tracks are moved inwardly, ear 77xpushing the forms inwardly so that the innermost stands directly beneath the hopper 65, which at that moment is in line therewith. The form previously withdrawn by the turret and having the bags thereon, namely the inner moisture-proof bag 89 and the outer preferably printed bag90, see Figs. 2, 32 and 36,is carried beneath the hopper 12,-While the turret is still elevated, where it receives its exact charge from the measuring chambers 9 and scale pans 1i. As will be noted, the form being filled receives the bulk of its charge while it is elevated; it is then lowered and raised while still in line with the hopper 12, before being moved laterally in linewith the packer, which will be herein- ,after set forth in detail. -The pawl-carrier 50 is designed to advance the turret the proper distance, but to insure the turret commg to rest at each quarter revolution in exact position so that the parts will properly function, a fixed vertically-disposed post 91, Fig.2, is en1pio \'ed, the upper end of the post being beveled or inclined so that 1t may readily enter the opening in the lug or hub 66, which at that time stands immediately above it. As the post stands at a distance from the axis of the turret, it will insure an absolute positioning of the parts. A similar arrangement of post and pawl-carrier is set forth in Letters Patent granted to Rufus L. Patterson'under date of March 23, 1897, and numbered 579,546. 92 designates a vertically-dis osed shaft, see Figs. 2, 5, 9, 12 and 17, the s aft assing through a sleeve 93, which in turn nds its bearing in a hollow post or column 94, secured upon the upper face of the table; Vertical endwise movement is imparted to said shaft 92 by means of cam 39, which acts upon a roller 95 carried by a lever or arm 96 fulcrumed upon shaft 60, the op osite end. of said lever being connectedto siiaft 92 by a link 97. The upper end of shaft 92 carries a spider frame 98, having four radially-disposed arms to which are attached the packer 99, the folder shaft 100, the paste receptacle supporting arm or shaft 101, and the packa e-ejectOr 102, all of which will be hereina ter set forth in detail. j

The lower end of sleeve 93 carries a bevel pinion 103 and a gear 104, the gear lying immediately above the inion; both being made fast to the sleeve. is will be seen upon reference to Fig. 17 gear 104 meshes with an idler 104, which in turn engages gear 48, and consequently said gear 104 is' given a partial revolution every time the pawl-carrier advances shaft 53' and its attendant parts. Sleeve 93 is, therefore, given a ste -by'-step, rotation equal to and in time with t e movement of the form-carrying turret. Said sleeve is formed as a downward extension of I a turret or casting 105, which may be termed the package-carrying turret. It is provided with four radially-disposed chambers or pockets 106, formed by the vertical walls 107,-which are, in the form illustrated, integral parts of the turret casting. Secured to the upper face of the table '1, beneath the turret 105, is an anvil or sup. lport 108, the su portextendin from a point eneath the ac er 99, aroun nearly to an o ening 109 ormed in the table in line with t e ackage-ejector 102, see Fig. 12. The anvi or support is curved so that it stands beneath the pockets and the bags carried thereby except when, the pocket and con-. tained bag come into line with the ejector,- .as 'ust noted. 50 n ironer or closer 110 (see Fig. 12) shown in the form'of a sector-shapedplate, is carried upon an arm '111 secured ,to the table, said ironer extending from the ointwhere the. paste is ap lied to .the folded ag to a po- '55 sition where t e jpackag isejected from, the

At such time thebag and form will be within onev of the pockets 106, with the bottom of the package resting fully and squarely upon the. anvil or see Fig. 29. The' upon shaft 100.

the compressed charge in the bag, or nested bags, as the case may be, in the pocket or chamber 106. The form-carrying turret is raised to its'highest point of elevation, and the shaft 92' is likewise moved to its uppermost position, the parts at such time occu ying the positions shown in dotted lines in I ig. 2.. The turrets are then rotated through the action of earns 36 and the connections before described, turret 64 moving so as to bring the stripped and emptied form in line with the discharging mechanism upon which the form is lowered, while turret brin s the openended filled bag or receptacle eneath the folding and indenting mechanism carried by shaft 100, where it comes to rest. This mechanism is best shown in Figs. 9, 12, 28, 29, 30 and 31-. It comprises a side folder or plate 1 12, pivotally connected adjacent to its outermost edge to the lower end of an armor lever 113; edge folders 114 and 115, pivoted respectively to the lower ends of levers 116 and 117 and an indenting plate 118, rigidly secured to thelower end 0 an arm orlever 119. A spring 120 is employed in conjunction with each of the edge folders, said s ring being of sufficient strength to give the lnner edge of theblade or folder a slight upward inclination so that they will hit the upstanding 105 sides of the bag at a point slightl higher than the blade or side older 112 w en they are moved inwardly. The arms or 113, 116and 117 arepivoted to lugs or ears 121, which project outwardly from the upper end of a sleeve 122, that loosely encircles the lower portion of the shaft 100, the lower end of said shaft being enlarged to prevent the sleeve from sliding off. The sleeve terminatesat its lower end infour feet 123, which are so positioned and related that when the folder is pushed down to its hmit the feet rest'upon the upper edges of the. uprightparallel walls 107. o the package-carrying turret,

feet are, however, given a sufficient-spread to permit the folders to pass in between them. The upper end of each lever 113, 1.15 and-116 is pivotally connected to a link 124, thelink's at their inner ends carrying pins which work in slots 126 125 formed in radially projectin arms 127" formed on a casting 128, slida 1y mounted- The upper end of lever 119 is beveled and works in conjunction with a cam 129, formed upon thecasting, said cam 130 levers.

coming into action to throw the indenting or folding blade 118 inwardly after the foldersprovided with an inwardly-extending off-set portion at its lower end, which has the effect of throwing the side folder 112 in over the bag in advance of the inward movement of the edge folders 115 and 116.

When the shaft 100 is elevated the parts stand in the positions shown in full linesin Figs. 1, 9 and 12, and in dotted lines in Figs. 28 and 29, the links 124 and the folder levers coming more nearly into'line and thereby throwing the folders outwardly. When the shaft is moved downwardly the feet 123 first come into contact with the walls 107, bringing the sleeve to rest. Continued downward movement of the shaft will cause the casting or frame 128 to be pressed down into the position shown in Figs. 28 and 29, which, as above stated, will force the upper ends of the levers outwardly and the folder blades inwardly, causing the upper end of the bags (or bag) to be folded in the manner illustrated in Figs. 33 and 34.

During the operation of folding, the turrets are at rest and so remain until the folder is raised entirely clear of the package. As soon, however, as this occurs, the turrets move a quarter turn, carrying thefolded package having one upstanding side beneath the paste-applying device. This comprises, in the form shown in Figs. 2 and 13, a receptacle or chamber 132, attached to the rod 101 and provided with an oscillating valve 133,

which controls the opening 134 formed in the bottom of the receptacle. The valve is provided with a laterally-extending arm or lever 135, which stands in the path of the arms 136 and 137, formed as a part of the upright 138. As the receptacle is moved down into contact with the partially-folded bag, the valve is opened, see full lines Fig. 13; when it is raised the valga is closed, as shown in dotted lines. After the paste or adhesive is applied to the bag, the package (still retained between the upright walls 107 and resting upon the support 108) is carried in beneath the ironer or closing plate 1 10. V end is thus turned down upon the adhesive, where it becomes fixed. Nhen the package thus sealed reaches a position over the opening 109 in the table, the ejector 102 descends, pushing the package endwise out of the pocket in the turret 105 and forcing it into the tumbler or package-reversing box 139, see Figs. 2, 9 and 35. 1

The tumbler is a rectangular box-like member, open from end to end, the opening in cross-section being equal to the outside The upstanding dimensions of the package, while the ends are flared to more readily admit the entrance of the package into the same. Said tumbler is provided at its midlength with stud axles 140, which find their bearings in brackets 141. One axle carries a bevel gear or pinion 142, which meshes with the similar gear 103 carried by the lower end of the sleeve 93, see Fig. 9. The other axle likewise carries a bevel gear 143, which meshes with a similar gear 144 mounted upon a shaft 145. Said shaft has secured to it a sprocket-wheel 146, a sprocket chain 147 passing about the wheel and a similar but somewhat smaller wheel 148. This latter wheel is secured upon a shaft 149, which overlies the stamp-containing box 150, and carries a block 151 pro,- vided with a yielding face 152, preferably of rubber, which comes into contact with the uppermost stamps and serves to feed the same forward, or in the direction of the tumbler, between a fixed lip 153 formed on the stamp-box or receptacle and a second lip 154 which overlies the other. The stamps are held and fed upwardly against the overhanging lips 155 of the box (see Fig. 10) by a follower 156 pressed upwardly by a weight 157 acting through a lever 158, rod 159, and connecting link 160. A knife 161, which extends down through the uppermost stamps (or labels) prevents the stamps from buckling and permits but one to be fed forward at a time.

As usual, one side of the stam -box is made removable or hinged, to aifor a ready means of replenishing the supply of stamps from time to time. The upper end of said stamp-box lies in a plane slightly lower than the lower end of the tumbler, and stands to one side thereof, see Figs. 9 and 35, while directly below the tumbler is located the stamp-applying mechanism. Said mechanism comprises an open-ended oblong chamber or box-like structure 162, somewhat larger in cross-section than the finished package. Extending across from side to side thereof, immediately adjacent to the upper end is a pair of rollers 163, so adjusted as to be slightly farther apart (measured from their proximate faces) than the width of a finished'package. Below said rollers, and mounted upon pins 164, extending inwardly from the sides of the box, is a pair of vertically-disposed brushes 165, which serve to holch the ends of the stamp close against the sides of the. package as it is forced downsive: Extending inwardly beneath the table and securedto-the member 2*, is an arm or bracket '167, see Figs. 2 and 25, which supports one end of'a track or way 168, the opposite end being secured to a second arm 169, best'shown 1n Fig. 3. Said way, as will be seen upon reference'to Fig. 25, stands to one side of and parallel to the stamp-applying box 162. Mounted uponthe way isa slide or block 170, which is connected to an adjustable link 170 pin-jointed at its opposite end' to the upper end of a lever 171. Said lever is fulcrumed between lugs 172,

uextendingupwardly from the cross-bar or 15: member: 56, and carries a roll which Works in the-grams]: way of cam 38. By reason of the shape of'the cam, the slide is moved over and back the full length of the track for each complete revolution of the cam, comin to rest at the left-hand end of the track an remaining in this rpjc' sition while a package "is being moged;.,,from the tumbler into the stamp-applying mechanism; The slide is provlded with a lateral extension 173, upon the end of which is formed the fixed 'aw or member 174 of the stamp-graspingdevice, the upper, movable jaw 175 being fixed upon the outerend. of a shaft 176 mounted in lugs 177 extending upwardly from the slide and the lateral extension. Shaft 176 also. carries a fin er 178, having a reversely-beveled end whic works in conjunction with a similarly beveled spring-pressed lunger 179, mounted in a barrel 180 secured to the upper face of the slide 170. When. the-finger lies above the plunger, the movable jaw is closed upon the fixed jaw and so held; when it lies below the plunger the movable jaw is held in its elevated position.

To effect a change in position of the finger and consequently the movable jaw, shaft 176 is provided With an arm 181,- the lower end of which stands in line with the end of a '9 fixed rod 182 secured to the bracket 169, and

: thebracket or arm 167.

also inline with a fixed finger .183 carried by Rod 182 serves to close the jaws when the slide has been moved to the extreme right, the jaws at such time grasping the stamp, which has previously een protruded from the box through the action of the "feeding block 151'. i

The jaws remain in such position until the slide nearly readhes its extreme position at theleft, when arm 181 comes into contact with finger 1 83 which shifts said arm, thereby se arating the jaws and releasing the stamp, w ich has meanwhile been drawnover the top of the stain -applying box or chamber directly belowtiedescending package.

To properl supply the requisite amount of paste or a hesive to the stamp in order to 'cause it to adhere to the package, suitable automatic mechanism is provided, which works in conjunction with the stamp-presenting mechanism just described. Secured to the lateral projection 173 of the slide is a rack '184, standing parallel to the track 168 and passing freely through a bearing-box -185 attached to and supported by the track. Secured to the upper face of-the slide is a 70.

cam 186, to which in turn is connected a bar 187'c'arrying adjacent to its outer end a secondcam 188, the cams being reversely inclined, as best shown in Fig. 22. The lower edge of the bar 187 rests in and is supported face of the bearing-box.

A paste or adhesive receptacle 189 is mounted upon the table, a flexible tube 190 extending downwardly therefrom and termi nating in a head or chamber 191. The tube and head are supported by a bracket 192,

pivotally connected to an arm 193 which in turn is pivotally connected to the support 2.

Head 191 is provided withan openingin its 81 .lower end, and a paste-applying roll 194 is are in the positions shown in Fig. 22, and the jaws have just engaged the protruded end of the stam at one edge thereof, the roller 198 is upon t e highest point of cam 186 and consequently the paste roll is likewise elevated. As the slide is moved to the left or from. the full line position, Fig. 24, to the dotted hne position, earn 186 will be withdrawn from beion 196 to engage the rack 184 and at the same time lowering the paste roll 194 'sothat it comes into contact with the advancingstampl The roll remains in this pos1t1on 'until cam 188 rides under roller 198 and again elevates the parts; meanwhile, the stamp will have paste applied to its Whole length.

As the package is forced out of the tumbler 115 139 by the next package above, see Fig. 35,.. its folded sealed end comes into contact with the stamp, and being forced downward entirely Within the box 162 the stamp is wrapped around the edges thereof, by the 120 actionfiof rolls 163 and brushes 165. Inasmuch as the uppermost package of the two shown in, Fi 35 will of necesslty' be moved down into t e position indicated b dotted lines in said figure, or as shown in ull lines,-.125 -Fig. 11, it becomes necessary to return the package into the tumbler in order that the stamp-withdrawing jaws may pass over to the stamp-box and withdraw another stamp.

For thispurpose, there is located adjacent to 130 by a groove or channel formed in the upper neath the roller 198, thereby permitting pin-
